Designing, planting and tending a landscape or garden is an avocation, a profession, a passion -and a nemesis of the most unpredictable and formidable sort. The pure joy that a great garden has to give back has a substantial responsibility that comes along with it. The landscape could be described as the responsibility for the health and happiness for a flock of living things. A lot of marbles have to be kept on the table-all at the same time. Every plant that dies on my watch-I take it very personally. Plants die routinely, and with astonishing regularity-in spite of knowledge and experience.

Some plants die from old age-every living thing has a lifespan. Some things die from a particularly fierce winter, or relentless rain, or extraordinary heat. Some things die from lack of water-of these deaths, I am particularly ashamed. Some things die from poor siting, or a a site whose ecology changes drastically-as in the loss of an old mature tree. The living community that describes my garden is ephemeral-fleeting. No tree, shrub, perennial, or garden experience comes with a lifetime guarantee. Should you decide to garden, the disappointments are part and parcel of the experience. Fortunately, a landscape has other elements that live longer.

Some elements in my landscape shrug off the water, the winter, the heat; the stone in my garden is the next best thing to indestructible. Stone persists in my landscape in spite of my neglect, poor science, or ignorance. What can I count on to be there every day, as best as I could count on anything? The stone stairs to my rose garden have been there as long as I have had my garden. I would guess it will still be there, when I celebrate my 100th birthday.

Stone in the landscape roughly refers to what we call hardscape. Stone beautifully populates those places to be, that soil to be retained, those spaces to entertain, and those walks with a natural material that provides an enduring hard surface. Stone is eminently capable of expressing your need for a change of grade. Stone provides paths and walks that enables travel from one space to another. Stone provides a beautiful and durable surface for a terrace. Compacted decomposed granite- shards 3/8 inch in diameter and smaller- makes level and hard surfaces that survive in driveways and garden paths, year after year. I so like balancing those living, and therefore fragile elements in a landscape with a crispy defined highly textural natural material that endures.

I am not a geologist-I am a gardener. But I can say with great conviction that the stone readily available to me regionally is always my stone of choice. Regional stone that is native to Michigan will look like it belongs in a Michigan garden. Stone native to the East coast, or west coast I can appreciate, but a sense of authenticity of place is important in making a landscape visually believable. No doubt an entire library exists which describes the color, texture and use of stone world wide. But I am primarily interested in stone that naturally occurs in my region of the country. In addition to bluestone and granite, Indiana limestone, and Valders stone from Wisconsin are favorites.

The fountain in my back yard is finished in Valders stone. The step down in submerged in water the entire season. This very high density dolomitic limestone is prized for its low water absorption. This makes it ideal for applications in or around water. Indiana limestone, also known as Bedford limestone, is principally comprised of calcium carbonate. The decomposition of marine animals at the bottom of the inland sea that covered the Midwest for countless centuries created limestone. The limestone quarried near Bloomington Indiana is acknowledged to be the highest quality limestone in the United States. It readily absorbs water; the limestone caps on my retaining walls have aged beautifully.

Should you need a hard and enduring surface or wall, natural and native stone will endow your garden with a sense of permanence. The formation of stone takes generations, and it will take generations to decompose. Do not be shy about inviting a natural element into your garden with proven longevity. It provides a quiet and appropriately natural foil for your plants.

I was a rock collector, as a kid. Every type of rock, every shape, every surface-I was enchanted. Nothing has much changed; I have a big love for all manner of rock. Stone carpeting the ground, stacked up like a wall, hand carved into a cistern, or half buried in a rock garden-I value it all. The stone slabs carpeting this conservatory floor-I have never seen anything remotely like it before. It has an exotic, architectural, and other-worldly look.

Stone cold, set in stone, stone faced, hard as stone -these are all phrases that describe a certain attitude that withstands the elements, the vagaries of nature, and popular sentiment. Stone comes with an aura of history about it. The eldest plant in my garden I estimate to be about 80 years old-a trifling age, compared to my stone. Relationships in a composition might be more important than the one, or the other. How an ephemral element interacts with a permanent element-always interesting. That great age one associates with natural stone has much to do with the creation of, and value, of stone garden ornament.

Stone ornament for the garden is a centuries old art and practice. A material which is virtually impervious and certainly accepting of the weather makes an ideal medium for sculpture, urns, finals, cisterns, plinths, and benches. Many antique pieces provides homes to thriving colonies of moss and lichens. Before Michaelangelo’s David was a sculpture, it was an ancient block of marble from the earth. Antique containers and urns hand carved from a single piece of stone are rare, and very costly. Dry cast limestone is a dry mix of cement, sand, mineral pigments and crushed natural stone, which is forced into molds, and vibrated under pressure until it fills the mold evenly. This method of manufacture makes stone garden ornament more readily available and affordable.

The stone in my garden is beginning to settle in. Plants have decided to take up residence in its crevices, and on its surface. I like how this makes me feel. This Belgian bluestone table with antique hand-carved corbel bases would indeed be lovely in a garden. Any gardener who has ever carried rocks around their garden, or had their fingers pinched setting a stepping stone knows that stone does not give. I like a material in my garden with this attitude.

I wrote this essay in a special capacity. I was so pleased that The Garden Designers Roundtable invited me to guest post with their group for the month of May. The Roundtable is a group of garden and landscape designers who write regularly on topics related to landscape design. This blog is a great read. www.gdrt.blogspot.com.
